INTERCHANGEAIBLE TRANSPARENT DISK ON SPARKQPRODUCING TOYS WITH CHANGING PICTURES.

Application filed Augult 1, 1927, Serial No. 209,880, and in Germany July 8, 1927.

, This invention relates toa spark-producsigned to secure in position differently ing toy with colored transparentdisks and is colored transparent panes m. A removable distinguished over toys of known type in knob n serves for holding the disk Z. that, above the spark-producing mechanism W hen the toy is being operated, the disk Z 6 on the shaft of the same a disk is loosely with the transparent panesmis rotated meremounted so that it can rotate with said shaft, ly by friction so that the sparks change color different colored transparent panes being only slowly. fixed on the disk by means of flaps. After 'lo interchange the transparent panes m the flaps have been bent up other colored first the knob n and then the disk 1 have to 10 transparent disks may be substituted. Owbe removed from the shaft d and the flaps k ing to this arrangement the playing child can have to be bent up, whereupon the transpar- 40' alter at will the color-effect, so that the toy ent panes can be removed and transparent becomes more interesting. I panes of other colors'inserted. On the accompanying drawing the inven-' I claim: 15 tion is illustrated, by way of example, A spark producing toy with changing pic- Fig. 1 is a side elevation, partly in section. tures comprising in combination with a disk Fig. 2 is a'top plan view. carrying cerium-stones and having apertures,

The driving mechanism 0 arranged in a an emery-disk underneath said cerium-stone casing a. and operated by a rack b communi- 'dlSk, a vertical shaft, and a drivin mecha-- i0 cates'a rapid rotation to a' shaft d. On the nism for rapidly rotating said shaft, a disk casingaone element o faspark-p'roducin dehaving apertures loosely mounted on said vice, for, instance an emery-disk f, is xed shaft above said cerium-stone disk flaps at the while the other element, i. e. a cerium-stone sides of said apertures, and differently g, fixed in flaps, is fixed to a disk' 2', loosely colored transparent panesgon the apertures 35 mounted on the shaft (1 so that it can be cou-. and removably fixed on said disk by means of pled with the same and having several apersaid flaps. tures it throu h which the sparks can pass.
